SUGAR-CANE CONVEYER.

SPECIFICATION forming part of Letters Patent No. 702,813, dated June 17, 1902.

Application filed March 26,1901. Serial No. 52,950. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES HENRY Mo- NALLY, a citizen of the United States, and a resident of Waipahu, in the Island of Oahu and Territory of Hawaii, have invented new and usefullmprovements in Sugar-Cane Conveyers, of which the following is a full, clear, and exact description.

My invention relates to means for handling sugar-cane, and has for its object to provide a self-propelled machine for conveying cane and loading it upon-cars, thereby saving a large amount of manuallabor and enabling a comparatively small number of men to do the work which now requires six to seven times as many men.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan of my improved self-propelled conveyor and elevator. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional elevation on the line 3 3 of Fig. 1. Fig. 4 is a sectional elevation on the line4 40f Fig. 3. Fig. 5 is a sectional detail on the line 5 5 of Fig. 4. Fig. 6 is a detail front view of the driving mechanism and the conveyer, and Fig. 7 is a sectionon the line 7 7 of Fig. 2.

The improved cane conveyor and elevator is provided with a suitable frame 1, having driving ground-wheels 2, j ournaled therein at each side. The frame carries a boiler 3, connected with independent steam-engines 4, each of which drives a shaft 5. Upon each shaft is mounted a pinion 6, engaging a gearwheel 7 upon a shaft 8, from which motion is transmitted by a pinion 9 and gear-wheel 10 to a shaft 11. With this shaft is mounted to turn, so as to be capable of sliding thereon, a clutchsection 12, movable lengthwise by means of a shifting mechanism 13 and adapted to engage another clutch-section 14, held against lengthwise movement, but loose relatively to the shaft 11, except when the clutchsections 12 14 engage each other. With the clutch-section 14 is rigidly connected a bevelwheel 15, engaging a similar wheel 16 on a shaft 17. This shaft carries a sprocket-wheel 18, connected by a chain 19 with another sprocket-wheel 20 upon a shaft 21. The two shafts 21 are provided with sprocket-wheels 22, receiving chains 23, consisting of inner links 24, alternating with outer links 24, and on'the pivot-bolts 25 are loosely mounted between the inner links 24 collars 25 Tothe links are secured transverse plates 26, with bolts 27 projecting between the links, and to said bolts are secured transverse slats 28, which together form a conveyor extending parallel with, the axes of the driving-wheels 2. The frame 1'oarries grooved guide-rollers 29, which engage the lower runs of the chains 23, and tension-rollers 30, Figs. 2'and 7, to take up slack.

On each of the shafts 11 is mounted to slide, yet held to turn therewith, a clutch-section 31, adapted to be moved by a shifting device 32 into engagement with another clutch-section 33, loosely mounted on the shaft, but held against longitudinal movement. WVith this clutch-section is rigid a pinion 34, engaging a toothed rim 35 on the driving groundwheel 2, Figs. 3 and 4.

At one end of the conveyer, formed by the slats 28, a trussed frame 36 is pivotally connected, as at 37, to the mainframe 1. The outer end of the frame 36 is adjustably supported by two rods 38, connected by a turnbuckle 39. The frame 36 carries an elevator 40, supported on sprockets 41, which receive the chains 42 of the elevator. The latter is of the same construction as the conveyer, ex-. cept that some of the slats 43 carry projections 44 for engaging the cane and keeping it from sliding down. by means of sprocket-chains 45, passing over Wheels 46 on one of the shafts 21 and wheels 47 on the lower elevator-shaft 48, the wheels 46 being larger than the wheels 47, so as to drive the elevator at a higher rate of speed than the conveyer.

The frame 1 at the end opposite to the driving ground-wheels 2 carries forks 49, mounted to turn about vertical axes 50 and carrying wheels 51. These forks when loose may be turned by suitable tools, or even manually.

In using the machine it is so placed as to travel lengthwise of the track on which stand the cars to be loaded with sugar-cane. The elevator 40 is arranged with its upper end The elevator is driven over the car. The sugar-cane is put on the conveyer at the end farthest away from the elevator and is carried along by the conveyer to the elevator, which raises it and dumps it into the car. When a car is loaded, both wheels 2 are driven so as to bring the machine abreast of the next car, and then the operation is continued. The shifting devices 13 and 32 allow of starting the machine and the conveyer and elevator or of keeping them stationary. The wheels 51 enable the machine to be steered. WVhen it is desired to swing the machine around, only one of the wheels 2 will be driven, so as to cause the machine to swing on the other wheel 2 as a pivot.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cane-loading machine comprising a frame provided with a driving ground-wheel on each side, two motors one at each side of the center of the frame, a clutch-controlled operating mechanism between each motor and a driving-wheel, a conveyer mounted in the frame, and a clutch-controlled operating mechanism between each motor and the conveyer, as set forth.

2. A cane-loading machine, comprising a frame provided with a driving ground-wheel on each side, two motors, one at each side of the center of the frame, a clutch-controlled mechanism between each motor and a drivin g-wheel, a conveyer extending transversely of the frame, a clutch-controlled operating mechanism between each motor and the conveyer, and an elevator at one side'of the frame and driven from the conveyer, as set forth.

3. A cane-loading machine comprising a supporting-frame, a pair of wheels at each side, one in front of the other of the frame, two motors, one at each side of the center of the frame, a clutch-controlled operating mechanism between each motor and one of the wheels of a pair, a conveyor mounted in the frame and extending between the wheels of each pair, and a clutch-controlled operating mechanism between each motor and the conveyer, as set forth.

4. A cane-loading machine, comprising a supporting-frame, a pair of wheels at each side of the frame one in front of the other, two motors, one at each side of the center of the frame,a clutch-controlled operating mechanism between each motor and one of the wheels of a pair, a conveyor mounted in the frame and extending between the wheels of each pair, a clutch-controlled operating mechanism between each motor and the conveyer, an elevator adjustably connected with one side of the supporting-frame, and means for operating the elevator from the conveyer, as set forth.

5. Inacane-loading machine, the combination with a wheel-supported frame, of a boiler on the frame, independent steam-engines on the frame one on each side of the boiler, and

connected therewith, a conveyer mounted in the frame, and an operating mechanism between each motor and one of the supportingwheels and the conveyer, as set forth.

6. In acane-loading machine, the combination with a frame provided with a driving ground-wheel on each side,and a transverselyextending conveyer mounted in the frame, of two independent motors, shafts each having a clutch-controlled connection with one of the drivingwheels, gearing between each shaft and the conveyer, and clutch-controlled gearing between each shaft and one of the motors, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES HENRY MONALLY.
